Yes, it's the great time to buy up now because than all the altcoins will skyrocket again! As for which ones i recommend AION, REBL, EBTCH. All of them are really low right now and are undervalued. Time to get in it is right now!
I completely agree with you - now is a very good time to buy many coins. Except for those you listed, I recommend buying a ripple, Tron, Iota. I'm sure they will show excellent growth.
Only Ripple, yeah, I just have strong faith in the future of Ripple in your list.
Tron and Iota all increased its value and enough with the potential of these tokens.
While, Ripple can increases its value more to make the market cap increases enough to provide a service for huge users in the future.
